SPECIFICATIDN forming` part of Letters Patent No. 290,510, datedDecember 18, 1883. Application led August 1.7, 1883. (Model.)

To all whom t may concern.-

Be it known that I, JOHN L; WILLIAMS, of Shenandoah, in the county ofSchuylkill and State of Pennsylvania, have invented a neu-r and ImprovedMiners Safety-Lamp, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a neuT and improved attachmentfor miners lamps, by means of which they can be extinguished veryquickly Without requiring the ,amp to be opened.

Reference is to be had to the accompanying drawings, forming part ofthis specication, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure lis a side view of a miners lamp provided with my improvement.Fig. 2 is a plan' view of the same. Fig. 3 is a cross-sec tionalelevation of the same. Fig. Iiis a perspective view oi the slidingsleeve on the Wick-tube.Y Fig. 5 is a perspective view of the Wick-tube.

The miners safety-lamp A is provided with alongitudinally-slottedwick-tube, B, and a picker-Wire, C, extending through a vertical tube,O, to the bottom of the lamp, from Where it can be manipulated, all inthe usual manner. I provide the lamp with an additional vertical tube,D', extending from the burner E to the bottom and terminating in arecess, F, formed in the bottom of the lamp. A wire, D, is passedloosely through the tube D', and to the upper end of the said Wire asleeve or tube, G, is fastened, which fits on the Wick-tube B, and isadapted to surround the same. The iiange B of the Wick-tube is providedWith a notch or recess, a, through which the tube D can pass. Then thebottom edge of the sleeve G rests upon the Wicktube flange B', theWick-tube projects slightly above the upper end of the sleeve and thelamp burns unmolested. If the dame is to be extinguished quickly, thelower end of the Wire D is seized and pushed upward to cause the sleeveto project above the upper end of the burner-tube. It then extinguishesthe flame.

It is of great importance to be able to extinguish the flame of a minerslamp very quickly in case fire-damp accumulates, so as to preventexplosions. Heretofore the Wiel; has been drawn into the Wick-tube bymeans of the picker-wire C, but by this means thelamp could not beextinguished quickly, especially if the miners became excited, Which isalways more or less the case when ire-damp accumulates. As it isabsolutely dangerous to open the lamp, the means for extinguishing thename must be so arranged that they can be operated Without opening thelamp.

Having thus described my invention, WhatI claim as new, and desire tosecure by Letters Patent, is

1. The combination, with alamp, of asleeve or tube adapted to slide onthe Wick-tube, and a Wire secured to the said sleeve or tube and passingthrough the lamp from top to bottom, substantially as herein shown anddescribed.

2. The combination, with a lamp having a recess in the bottom, of asleeve or tube on the Wick-tube and a wire extending from the said tubeinto the recess in the bottom oi the lamp, substantially as herein shownand described.

3. The combination, with a mincrs lamp, of the tube D', extending fromtop to bottom, the Wire D in the said tube, and the sleeve G, secured tothe upper end of the Wire D, and adapted to slide on the wick-tube,substantially as herein shown and described.

4. The combination, with a miners lamp, of the tube D, extending fromtop to bottom, the wire D in the said tube, the sleeve G, secured on theupper end of the Wire, and of the Wick-tube B, having a iiange, B',provided with a notch, a, for the tube D', substantially a herein shownand described.
